<p>Pulsating stepless gear box comprises a transmission mechanism for transferring a uniform rotating motion to variable-speed rotating motion, an output mechanism for outputting the power and a speed control mechanism for varying position relation between the parts of the speed control mechanism. The output mechanism employs 2Z-X typed differential wheel set in the same direction as an output means, and two center wheels of the differential wheel set are respectively connected to an input end and an output end of the transmission mechanism. A rotary arm is used to output the power. The pulsating stepless gear box outputs the power step by step by means of a combination of two or more transmission mechanisms and differential wheel sets between which there are a phase difference.</p> |
